Retroviruses (within Riboviria)

~1.25 Billion years ago (+/- 200 million)

Stitch themselves permanently into the host’s genome

Retroviruses emerged by transforming “jumping genes” into infectious agents, mastering the ability to rewrite a host’s permanent genetic code.

Appearing as complex eukaryotes diversified, Retroviruses evolved by equipping mobile genetic elements (retrotransposons) with “stolen” structural proteins. Using the enzyme reverse transcriptase, they flip the flow of information from RNA back into DNA, allowing them to stitch themselves permanently into the host’s genome and hide for generations.

Prestwood writes on science-first philosophy, with particular attention to the convergence of disciplines. Drawing on his TST Framework, his work emphasizes rational inquiry grounded in empirical observation while engaging questions at the edges of established knowledge. With TouchstoneTruth positioned as a living touchstone, this work aims to contribute reliable, evolving analysis in an emerging AI era where the credibility of information is increasingly contested.
